The fuel for heatingniy improved heater is exemplified as gas,'although other fuel, either solid liquid .or gaseous, may be e1nployed'; A fire-box 11 has the fuel element therein, represented as'a gas-burner 12. The body of the fire-bdx is shown of rectangular form. V, v V

Passages 15 for the fluid being heated are shown rectangular in cross-section. provided with upper Walls 16,- flOWGI" walls 17 and side walls 18, 19. Tliese passages are open-ended as shownat 20, 21.. The walls forin flat rectangular tubes'made out of metal sheeting connected; at their edges for making tight joints. The lower one'of these passages, has

side walls 22, 23, Whichproject downwardly and connect with the fire-box with a sealed ]011'1t.

vThese passages are arranged one abot'e the other in the heater, and are spaced. apart by spaces 25, which form passages crossingly arranged with relation to the passages 15, and are also preferably rectangular in cross-section; I K Y The respective ends ofthe'upper wall and the lower wall of t'he respective passages 15 are bent away from said passages to form side walls 26,"27,"for the respective passages and have sealed joints forfor ning-sa id crosspassa ges 25. The passages 25 are open-en (1- ed as shown at 28,29,

Deflectors 31, 32, 33,134,35, project from one oftlie ends of the respective cross-pas sages 15 into a niaifn' supply passage 36 formed by the side walls atoneof the sides of, the

assags'eae wall 37 parallel wit-h said sidesand merging with the deflector 3,5,,wliich de-. flector io rinsthe bottonrof said inain supply passage, the ends of the supply passage beingfor ned by end walls 38, 39. Theiends of the deflectors are connected with said end walls. The passage 36 forms the supply passage for the fluid being heated.

These deflectors are shown as successively extending increasing distances into the supply passage for respectively shunting portions of the current in the supply passage into the various cross-passages 15.

' A secondmain passage 41 is at the other end ofsaid cross-passages 15, and is formed for instance by the other side walls 26 of said cross-passages 25, a wall 42 parallel therewith i and end walls 48, 44. The passage 41 is the I discharge passage for the cross-passages 15.

, Deflectors 45, 46, 47, 48 and 49 extend into sa d second discharge passage preferably fromthe upper walls of said cross-passages 15, except irom the lowest one of said crosspassagess- These deflectors preferably also extend into said discharge passage to various extents, the upper one 45 of the deflectors forming the upper wall of said discharge.

' passage. The supply passage 36 and the discharge passage 41, are preferably of rectangular form 1n cross-section, extending crosswiseiof the .cross-passages throughout the lengths ofthe cross-passages25.

1 The supply passage and the discharge sage preferably-extend up and down and havethe fluid: to be heated,.instanced as air, preferably forced downwardly therein, the currentsofair being divided between said I sup plypassage and saiddischarge passage into'a multiple or 'cross-passag'es for dividing the inconnng a1r into a number of cross-currents which are heatedto' different extents according to their distance frointhefire-box,

these cross-currentsbeingagain united into a descending current'ihaving equalized temperature, this descending current being preferablypassed around the fire-boxt'or receiving additional heat r The lower end 50 of the wall 420i the second main passage" is :bent to form .a de-- ilector' for directing the combined currents into the lowermost one ofthecross-passage 15, the lower part of sald lowermost crosspassage 15 being formed by the upper wall of the'fire-box.

The direction of travel of the fluid being heatedinthe lowermost cross-passage 15 is reverse to the direction of travel of said fluid through the cross-passages 15 thereabove.

- A deflector at the end of the lowest cross-passage 15 directs the current of heated fluid into a passage 56' which is shown as a passage extending about the fire-box. The inner side wall of SELIClBXbGIISlOH is formed 'by thje fire-box, the out-er side wall being passages and extension passages is indicated by the arrows a. The air is received-through an inlet port 65, and is exemplified as having a generally downward course and a course which is crosswise to the passages 25 and is around the bottom of the fire-box and then ascends in the ascendingstretch of the passage andis received through a discharge port 66 nisald passage.

in a downward direction reverse to the direction of natural flow of heated fluld, which would be upward. The fluid, namely the air to be heated, is forced downward, asby means of a blower 71, which comprises an electric motor 72 and a fan 7 3 in an intake chamber 74, towhich apipe 75 may lead from a suitable source, as trom the outside air or. the air may be received through said pipe from the house or rooms or space to be heated. Ahood 76 is located between the blower and the inlet portand directs the air into the main air supply passage of the heater. The heated air is discharged through the outletport 66. It may, if desired, enter a hood 7 9, which directs the heated air into a drum 80, from which suitable heating pipes, shown at 81, and provided with the usual dampers 82, direct the heatedair to the (19-. sired point of use, as to the various rooms in the'dwelling or to other spacesito be heated, or said heated air may assume any other course. i The products of combustion are received through an opening 85 in the rear wall of the fire-box. The respective upper walls and lower walls of the passages 15 spaced above the fire-box form respectively the lower wall and the upper wall of the passages 25, crossingly arranged with relation to the firstnamed passages, the side walls of said lastnamed passages being formedby the bent ends of the upper and lower walls of the first named passages'15 spaced above the fire-box, as hereinbefore explained.

Theends ofneighboring passages 25 above one another are connectedatthe respective ends of said passages by means of deflectors 86, 87, which are formed in deflector sheets 88, 89, at the respective endsof the passages 25, and are suitably connected with the respective sides o'f-alternating passages15, and with the fire-box, by means of sealed joints for forming connecting passages ,90, 91, at the respective ends of the passages 25, and a connecting passage 92 between the opening 85 I ,The fluid being heated is preferablyci orced crimas-sea:

and the lowermost cross p'assage 25. The-1a fluid passage 15.

AL serpentine passage extending back and forth and in general upward direction is thus provided for the products of combustion,

An outer casing 96 is provided for the heater which may be provided with a lining of in sulation 97. w I s I a I The passages 15 and 25 extend substaiitially' throughout the horizontal crosssectional area of the heaten v a a.

In my improved device the incoming co urnn of air is divided for being'apportioned among the respective crosspassages'1'5,

the successive deflectors extend into the sup-1 ply passage in ncreasing ratio. Thus assuin ing that 700 cubic feet of air per minute are being delivered to the intake opening and there are fire cross-passages to be fed by said supply passage, the deflector 31 extends into the supply passage to divert one-fifth of the incoming air or other fluid intothe upper cross-passage 15. The next deflector 32 armor tlie supply passage, for deflecting about one-half of th'e'balance OfShiClHlfiiil iirrentinto the fourth cross-passage 15, the balance of the maincurrent being deflected into the bottom cross-passage l5 spaced from the fire-box openiiigat that side of the heatheatedto each of the crossfpassages, nai'nel -y, onehundred and forty cubic ieet of air in the example stated;

The upper deflector45 extends across the entire cross-sectional areaof the main outlet or discharge passage 41; the sec ond deflector 46 extends into the discliarge passage for about one-half the cross-seek tional area of said discharge passage; the ti'iirddeflector 47 extends into the crossse'ctiona-l area of the discharge passage to cover one-third its area; the iourd'e'flector ex ends into said discharge passage for extends into said discharge passage for one fifth its area, for receiving proportional discharges from the respective cross-passages l5 spaced from the fire-her; and combiningthe discharges irom said cross-passages and causing the same to be mingled and moved into the lowermost passage 15',-Vl1f6- in it moves in opposite direction.
